A study on the preparation of adsorbent from Ananas comosus leaves plant by thermo chemical activation and its adsorption behavior of the removal of malachite green

Adsorption of MG dye by the Activated Ananas Comosus Leaves Carbon was studied through the batch equilibrium techniques. The influence of contact time, initial concentration of dye, initial pH and other ions were experimentally verified. The Freundlich and Langmuir models tested to describe the equilibrium isotherm reactions. The kinetic processes of dye adsorption on Ananas Comosus Leaves Carbon were described by applying pseudo second order, Elovich model and intra- particle diffusion model and the kinetics data indicate that the adsorption follows pseudo second order kinetic surface adsorption. The equilibrium and thermodynamic parameters of the adsorption process were determined from the sorption behavior of AACC and the results indicate that the adsorption of MG dye by AACC is follows spontaneous nature and endothermic process.
